NARI moved NNE in the past 24 hours and weakened into a category 1 typhoon. At 06 UTC, NARI was centred 250 km (140 NM) SSW of Taegu (Daegu), South Korea.

百合於過去 24 小時向東北偏北移動並減弱為一級颱風。於 06 UTC，百合集結在大邱西南偏南約 250 公里 (140 海里)。

It is expected that NARI will travel along the northwestern periphery of the steering subtropical ridge. Together with the effect of the westerlies, NARI will accelerate in the NNE/NE direction.

受到西風帶的影響，百合將於餘下時間沿副熱帶高壓脊西北部向東北偏北至東北移動。

As of 06 UTC, NARI's T-number was 4.5 or equivalently carried 75 knots wind (typhoon category 1). NARI should weaken throughout the forecast period as it will be subjected to lower sea surface temperatures and higher vertical wind shear.

在 06 UTC，百合的T號碼為4.5，即 75 節的風速 (一級颱風)。百合將於餘下時間因受較冷的海水及強烈垂直風切變的影響而減弱。

No threat to Hong Kong is expected within the next 72 hours.

百合於未來的72小時將不會對香港構成任何影響。

NARI moved NNW in the past 24 hours, intensifying rapidly into a category 4 storm last night. It weakened slightly today and is now a category 3 typhoon. At 06 UTC, NARI was centred 480 km (260 NM) S of Cheju (Jeju), South Korea.

百合於過去 24 小時向西北偏北移動並於昨晚增強至四級颱風，及後稍為減弱為三級颱風。於 06 UTC，百合集結在濟州島以南約 480 公里 (260 海里)。

A broad subtropical ridge is anchored E of NARI. With the ridge as the primary steering force, it is expected that NARI will travel N across the ridge axis in the next 36 hours. After that, the westerlies will introduce E component to the track to NARI and thus it will be subjected to an accelerated motion towards the NNE/NE.

一個廣闊的副熱帶高壓脊正處於百合東部，百合將於未來 36 小時向北移動，橫過副熱帶高壓脊的脊線。隨後百合將會受到西風帶的影響而轉向東北偏北至東北移動。

As of 06 UTC, NARI had a 10 NM off-white eye surrounded by light gray ring as appeared on the satellite imagery, which gave a T-number of 5.5 or equivalently carried 105 knots wind (typhoon category 3). Due to excellent poleward outflow, NARI intensified at greater than climatological rate last night. It is forecast that NARI will remain strong when crossing the ridge axis due to good poleward outflow and moderate vertical wind shear. NARI's strength should decrease after crossing the ridge axis as it will be subjected to lower sea surface temperatures and higher vertical wind shear.

在 06 UTC，百合的T號碼為5.5，即 105 節的風速 (三級颱風)。受到極好的極向輻散通道影響，百合在昨晚急速增強。預料繼續受到良好的極向輻散通道及中等的垂直風切變影響，百合可於未來 24 小時維持強度。當百合橫過脊線以後，它將受較冷的海水及強烈垂直風切變的影響而減弱。

No threat to Hong Kong is expected within the next 72 hours.

百合於未來的72小時將不會對香港構成任何影響。

20 HKT, 2007/09/16 (or earlier 或更早)

NARI moved WNW turning to NW in the past 24 hours, intensifying rapidly during the same period. At 06 UTC, NARI was centred 140 km (80 NM) SSE of Okinawa.

百合於過去 24 小時向西北偏西至西北移動，並迅速增強。於 06 UTC，百合集結在沖繩島東南偏南約 140 公里 (80 海里)。

A broad subtropical ridge is anchored ENE of NARI. With the ridge as the primary steering force, it is expected that NARI will travel NW along the southwestern periphery of the ridge in the next 12-24 hours, gradually turning to NNW. Between t+24 and t+36, NARI will cross the ridge axis, and will be subjected to the westerlies to induce a recurvature.

一個廣闊的副熱帶高壓脊正處於百合東北偏東部，百合將於未來 12 至 24 小時沿該脊之西南部向西北轉西北偏北移動。預料百合將會在 24 至 36 小時之後橫過副熱帶高壓脊的脊線，隨後受西風帶的影響轉向東北移動。

As of 06 UTC, NARI's T-number was 5.0, or equivalently carried 90 knots wind (typhoon category 2). Due to excellent poleward outflow, NARI has intensified at greater than climatological rate during the past 24 hours. It is forecast that NARI will strengthen at climatological rate before crossing the ridge axis due to the improving poleward outflow and low to moderate vertical wind shear. NARI's strength should decrease after crossing the ridge axis as it will be subjected to lower sea surface temperatures and higher vertical wind shear.

在 06 UTC，百合的T號碼為5.0，即 90 節的風速 (二級颱風)。受到極好的極向輻散通道影響，百合在過去 24 小時急速增強。預料繼續受到良好的極向輻散通道及輕微至中等的垂直風切變影響，百合可於未來 24 小時以氣候平均值增強。當百合橫過脊線以後，它將受較冷的海水及強烈垂直風切變的影響而減弱。

No threat to Hong Kong is expected within the next 72 hours.

百合於未來的72小時將不會對香港構成任何影響。

A low pressure area E of Taiwan intensified into a tropical depression this morning. It then strengthened rapidly, attaining tropical storm level at 06 UTC and was named NARI. At 06 UTC, NARI was centred 670 km (320 NM) SE of Okinawa, moving NW in general.

一個位於台灣東方的低壓區今晨增強為一熱帶低氣壓，並於下午快速增強至一熱帶風暴，命名為百合。於 06 UTC，百合集結在沖繩島東南約 670 公里 (320 海里)，大致向西北移動。

A broad subtropical ridge is anchored NE of NARI. With the ridge as the primary steering force, it is expected that NARI will travel NW along the southwestern periphery of the ridge. Between t+48 and t+72, NARI will cross the ridge axis, and will be subjected to the westerlies to induce a recurvature.

一個廣闊的副熱帶高壓脊正處於百合東北部，百合將沿該脊之西南部向西北移動。預料百合將會在 48 至 72 小時之後橫過副熱帶高壓脊的脊線，隨後受西風帶的影響轉向東北移動。

As of 06 UTC, NARI's convection wrapped 0.7 on the log10 spiral which yields a T-number of 3.0 or equivalently 45 knots wind (tropical storm). It is forecast that NARI will strengthen at less than climatological rate before crossing the ridge axis due to the combined effect of improving poleward outflow and restricted equatorward outflow, together with generally warm sea surface temperatures and moderate vertical wind shear. NARI's strength should decrease after crossing the ridge axis as it will be subjected to lower sea surface temperatures and higher vertical wind shear.

在 06 UTC，百合的T號碼為3.0，即 45 節的風速 (熱帶風暴)。受到轉好的極向輻散通道、被阻礙的橫向輻散通道、較暖的海水及中等的垂直風切變的影響，百合可於未來 48 小時稍為增強至一級颱風。當百合橫過脊線以後，它將受較冷的海水及強烈垂直風切變的影響而減弱。

No threat to Hong Kong is expected within the next 72 hours.

百合於未來的72小時將不會對香港構成任何影響。
